Performance Analysis of AODV, DSR & OLSR Protocols in MANET

  • Jadhav Purushottam Sadashiv, Dr. E. Kanniga


A mobile ad hoc network (MANET) consists of wireless mobile nodes. The communication between these nodes happens without any centralized control. MANET is a self-organized and self-configurable network where the mobile nodes move arbitrarily anywhere in a network. The mobile nodes has a feature like routers which can forward and receive the packets with other nodes. Routing is a critical issue in MANET and hence the focus of this paper is on performance analysis of routing protocols. I compared the three routing protocols i.e. AODV, DSR and OLSR. Simulation tool will over here is QualNet Simulator – Network Simulator Software. The performance of these routing protocols is analysed by three metrics: Average end-to end delay, energy consumption and throughput based on node density. All the three routing protocols are compared and explained with results using QualNet simulator tool. The comparative analysis is carried out of all the three protocols which concludeswhich routing protocol is the best one for mobile ad hoc networks considering multiple parameters impacting the network.
